1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?

• A. Rigor mortis
• B. Postmortem decomposition
• C. Algor mortis
• D. Livor mortis

Correct answer: C

Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.

3. Which of these specific measurements is the best index of a child's general health?

• A. Body mass index
• B. Height and weight
• C. Head circumference
• D. Chest circumference

Correct answer: B

Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.

4. A client is being assisted with ambulation in the hallway using a gait belt when they become dizzy and start to faint. What is the first action the nurse should take?

• A. Stand behind the client and prepare to catch them if they fall
• B. Assist the client to sit in the nearest chair or slide down along a wall
• C. Grasp the client under the arms and pull them upward
• D. Call for help from nearby staff

Correct answer: A

Rationale: If a client becomes dizzy and starts to faint while being assisted with ambulation, the nurse's first action should be to assist the client into a sitting position to prevent or reduce the impact of a fall. This can be done by guiding the client to sit in the nearest chair or sliding down along a wall for support. Option A is incorrect because standing behind the client may not prevent a fall and could potentially lead to injury. Option C is incorrect as pulling the client upward may worsen the situation. Option D, calling for help, is not the first action to take when the client is at risk of falling.

5. You are preparing to admit a patient with a seizure disorder. Which of the following actions can you delegate to an LPN/LVN?

• A. Complete admission assessment.
• B. Set up oxygen and suction equipment.
• C. Place a padded tongue blade at the bedside.
• D. Pad the side rails before the patient arrives.

Correct answer: B

Rationale: The correct answer is to delegate the task of setting up oxygen and suction equipment to the LPN/LVN. This task falls within their scope of practice and can be safely performed by them. Completing the admission assessment (Choice A) typically requires a higher level of assessment and critical thinking, making it more appropriate for a registered nurse. Placing a padded tongue blade at the bedside (Choice C) involves potential airway management, which is a more complex task and should be done by a higher-level provider. Padding the side rails before the patient arrives (Choice D) is a task related to patient safety and should be done by the healthcare team as a whole, not solely delegated to an LPN/LVN.
